Yes, the IOS NAT can change the DNS reply payload, and change the global IP
to local IP, but only when static NAT is configured on Router.
Also there is a keyword that you can use to turn off the feature starting
IOS 12.3 or 12.2T

Subject: DNS and NAT
Is there a solution within IOS to intercept DNS resolution? My issue is
that I have hosts and a WWW server on the same segment. All are being
NATed. The DNS servers sits outside of the Network/NAT and tells the rest
of the enterprise the way to get to the WWW server use this global IP which
has a static translation to the WWW server. The issue is that when the
local host do a DNS lookup they are getting the global IP rather than the
local IP.
I know the PIX can do this with the dns and alias keywords but I am looking
for an IOS solution.
Thanks,
Nir
